STAY-STRIP.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed April 18, 1907. Serial No. 368,863.

To all whom it may concern:

Be it knownthat we, CHARLES H. Cnowrum and GEORGE W. VVArsoN, citizens of the United States, residing at Nashua, county of Hillsboro, State of New Hampshire, and

at Swampscott, county of Essex, Commonwealth of Massachusetts, respectively, have inventeda certain new and useful Improvement in Stay-Strips, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to a-stay and binding strip which is to be folded along a straight longitudinal line in order to adapt it to be attached to two surfaces at an angle sides which is necessary in order to make a good and neat piece of work. When the stay strip is put on by machine, it is sometimes the practice to first crease the strip along the intended folding line in order to enable it to be accurately folded. Sometimes a longitudinal crease or groove is formed in the face of the stay strip. This latter method is somewhat objectionable as it weakens the stay strip along the folding line. When strips of the kind referred to are used for binding purposes, or for reinforcing, it is often times necessary that the strip should be folded in a straight line before or at the time the stay is applied.

The object of our invention is to provide a stay or binding strip so constructed that it will readily fold along the particular line desired without reducing the thickness or removing any part of the body' or the adhesive along the intended folding line.

The invention consists essentially in attaching athread'or cord to thestrip, preferably on the surface thereof, and along the line on which the strip is to be folded.

The invention will be fully understood from the following description taken in con-. 5 nection with the accompanying drawings,

' tached to a corner of -a box.

and the novel features thereof will be particularly pointed out and clearly defined 1n the claims at the close of the specification;

In the drawings, Figure 1 is a perspective on an enlarged scale showing a piece of stay strip embodying the invention; Flg. 2 is a perspective view showing a-roll ofstay strip constructed like that shown in Fig. 1 with one end partially uncoiled and at Fig. 3 is a perspective view of a modification in which the stay strip is composed of two layers secured together by an adhesive and the thread is inclosed between the two layers Referring to the drawings,-A represents the stay or binding strip which for convenience in use is preferably wound into a coil B.

C represents a box to which a portlon of the stay strip A shown in Fig. 2 has been applied.

The body or backing 7 of the strip 18 composed of cloth or paper or other suitable material such as is used for stay strips or for binding purposes or for reinforcing, and has upon one face a coating 8 of adhesive material of suitable composition which may be applied in any well known way. Secured to the ammed face of the strip is a thread or cor 9 which extends lengthwise of the strip along the line where it is intended that the strip shall-be folded. This thread may be attached to the face of the strip in any suitable way, one way being by causing the thread to be laid on the strip after the adhesive has been applied and while it is still moist, so that thereby the thread will be attached to the gummcd side of the strip. Any suitable and well known means whereby the thread may be laid in position on the gummed strip in, proper alinement may be employed.

It is obvious that the thread may be secured to the surface of an ungummed strip or the ungummed surface of a gummed strip by applying adhesive to the thread itself or to a narrow line lengthwise of the face of the strip where the thread is to be attached, leaving the face of the strip to which the thread or cord is applied substantially free from any adhesive. The thread thus applied is e ually effective to insure the even folding o the strip.

When it is desired to form the stay strip from two layers of material, as is frequently done, cloth for example forming one layer ducing the thread or cordbetween the layers and paper the other, the layers are usually applied to the corners of'the taxe to be 25 secured together by an adhesive in a manner well known tothose skilled in the art.

We contemplate the embodiment of our invention in such ,a compound stay strip as that which we have just referred to which is shown in Fig. 3 of the drawings, but intro of which the compound strip is composed when they are being joined together. The

resulting stay strip composed for example of a layer of cloth 10 and a layer of paper 11 united in the well known manner, see Fig. 3, will, when our invention is applied thereto, have a thread or cord 9 extending between themalong the line on which it is desired they shall fold when employed as a stay strip binding or for similar purposes. y

We find in practice that the thread attached to or contained within the stay strip as heretofore described is effective to cause the said stay strip to bend along the line of the thread when the stay strip is fed through the machine by means of which the stay is stayed. I

We claim as our invention:

1. A stay or binding strip having a thread secured thereto along the intended folding line of the strip.

2. A stay or binding strip having secured to one face by adhesive material a thread extending lengthwise of the strip along the intended folding line.

3. A stay or binding strip composed of two or more layers united together having between said layers a thread extending along the intended folding line.

In testimony whereof we aflix our signatures, in presence of two witnesses. v
